DEVICE FOR DRAWING EFFERVESCENT LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 680,499, dated August13, 1901.

Application filed January 25, 1901- To aZZ whom it may concern.-

Be it known that I, J OlEIN NAGELDINGER, a citizen of the United States,residing in New York, borough of Manhattan, in the State of New York,have invented certain new and useful Improvements in Devices for DrawingEfiervescent Liquids, of which the following is a specification.

This invention relates to certain improvements in the device for drawingoff eifervescent liquids for which Letters Patent of the United Stateswere granted to me, No.660,331, dated October 23, 1900, the improvementsbeing designed with the view of utilizing the pressure-relief chamberalso as a dischargechamber, so that a separate discharge-nozzle isdispensed with and the construction of the device considerablysimplified; and the invention consists of a device for dispensingefiervescent liquids which comprises a pressure-relief chamber having adischarge-nozzle at its lower end, a socket for supporting said chamberat its upper end, said socket being provided with a liquid-supplychannel and a pressure-relief channel, a valved supply-pipe connectedwith said supply-channel, a spring-actuated pressure-relief valveretained normally in position for closing the pressure-relief channel, avalve-chamber for said pressure-relief valve provided with apressure-relief tube, a spring-actuated liquiddischarge valve, thespindle of which is connected with the spindle of the pressure-reliefvalve, a sliding casing guided on the chamber of the pressure-reliefvalve and connected with the upper end of the spindle of thepressure-relief valve, and means for operating successively the supplyvalve and the pressure-relief and discharge valves; and the inventionconsists, further, of certain details of construction and combinationsof parts,which will be fully described hereinafter and finally pointedout in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved device for drawing effervescent liquids shown in sectionthrough the discharge-nozzle at the lower end of the pressure-reliefchamber. Fig. 2 is a plan View of Fig. 1. Fig. 3 is a vertical centralsection of my improved apparatus on line 3 3, Fig. 2; and Fig. 4 is ahorizontal section on line 4 4, Fig. 3.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a pressure-relief chamber, whichis preferably made of glass of suitable thickness to withstand thepressure of the effervescent liquid that is to be supplied to and drawnofi from the same. The pressure-relief chamber-A is preferably made ofbulb shape and provided with a cylindrical neck at its upper end,whichis supported in a socket A. The chamber is provided at its lower endwith a dischargenozzle a. The upper end bears against an elasticpacking-ring a, seated in an annular recess in the socket. The socket Ais provided with an interior screw-thread that engages anexteriorly-threaded collar A that is provided with a shoulder a againstwhich the lower'end of the socket abuts, and the upper end of which isprovided with an inwardly-bent flange that abuts against an exteriorshoulder on the upper part of the neck of the pressure-relief chamber A,a packingring a being interposed between the neck of the chamber and thecollar A so as to produce thereby a tight and reliableconnection betweenthe socket A and the chamber A. The socket A is connected by a valvedsupply-pipe B with a vessel or fountain containing the carbonated liquidunder pressure, said supply-pipe being provided with a spring-actuatedvalve B, that is opened by the pressure of a f ulcrumed elbow-lever 13against the stem of the valve,which extends through a stuffingbox to theoutside, as shown clearly in Fig. 4.

The socket A is provided with a stationary handle H, which extendsradially therefrom, as shown in Figs. 1, 2, and 4:. A handle H isfulcrumed by-an intermediate pivot-link h to the stationary handle, sothat when the palm of the hand rests on the movable handle the fingerscan readily grasp the stationary handle H and on pressing the handlestogether move the handle 11 toward the stationary handle H. handle H isprovided with a circular enlargementor yoke H that extends around and ispivoted to a cylindrical sliding casing D, that is closed at its upperend and guided on a cylindrical valve-chamber A of the socket A. p

The cylindrical valve-chamber A is closed at its upper end by ascrew-cap A through The end of the fulcrumed IOO which and the slidingcasing D passes the stem E of the pressure-relief valve E, which stem isscrewed into the top of the casing D and tip 6 of the same, as shown inFig. 3. A helical spring 6 is interposed between the screw-cap A and thepressure-relief valve E, said spring pressing the valve in downwarddirection on a central pressure-relief channel in the socket A, so as tokeep said channel closed when the pressure-relief valve is in its normalposition. The cylindrical valve-chain her A is provided with a blow-offtubefabove the socket A, as shown in Figs. 2 and 3. The spindle E isextended in downward direction through the bore 0, which bore is oflarger diameter than the spindle, and is provided with an enlarged andscreuethreaded end g,

on which is screwed a cylindrical casing or,

sleeve g, the lower end of which is guided on the stem 9 of thedischarge-valve G, which is i of sufficient size to close thedischarge-nozzle a. The upper end of the stem g is provided within thesleeve g with a cap or shoulder 9 between which and the threaded end ofthe spindle E a helical spring g is interposed, which presses thespindle g in downward direction, so as to keep the discharge-valvenormallyin position for closing the dischargenozzle, as shown in Figs. 1and 3.

My improved apparatus for drawing effervescent liquids is operated asfollows: The tumbler or other vessel into which the carbonated liquid isto be discharged is held in one hand below the nozzle a, while the otherhand is used for operating the device. The palm of the hand is placed onthe movable handle H, so that the fingers can grasp the handle B of thesupply-valve and move the same in the direction of the arrow shown inFig. 2, thereby opening the supply valve against the tension of itsspring, so that immediatel y carbonated liquid is supplied from thefountain through the connecting-channel c in the socket A into thepressure-relief chamber, in which the liquid rises until an equilibriumof pressure is established between the pressure-relief chamber and thefountain. As soon as this occurs the handle of the supply-valve isreleased and the handle H grasped by the fingers, so as to produce thedepressing of the handle H, and thereby the lifting of the slidingcasing D and the pressure-relief valve E against the tension of thespring 6 of the latter, so that the pressure-relief valve is lifted andthe excess of gas in the upper part of the pressure-relief valve blown01f through the pressure-relief channel 0 and tube f. Thedischarge-valve is held in its normal closing position on thedischarge-nozzle a of the pressure-relief chamber by the tension of thespring in the sleeve 9 until the lower contracted end t of the sleeveabuts against the shoulder or cap g of the stem g and lifts thedischarge valve against the pressure of the liquid in the chamber A, sothat the nozzle is opened and the liquid permitted to flow by gravityinto the tumbler held below the same, air enterin g through the tube fand channel 0 into the chamber A above the descending liquid. The shortdistance between the shoulder g and the lower end t of the sleeve allowsfor sufficient lifting of the pressure-relief valve, so that theblow-off of the excess of gas in the upper part of the chamber can takeplace before the discharge-valve is opened and the liquid dischargedthrough the nozzle of the chamber. The blowing 0d of the surplus gasfrom the pressure-relief tube f and the discharge of the carbonatedliquid from the chamber take place in quick succession, as the upwardmotion of the yoke of the movable handle produces the opening of thepres sure-relief valve-and the discharge-valve in quick succession, theescape of the gas being indicated by the slight noise which takes placeimmediately before the flowing of the liquid through the nozzle. Whenthe tumbler is filled, the discharge is interrupted by releasing themovable handle, so that the pressure-relief and discharge valves areimmediately returned by the tension of their respective springs intotheir normal positions on their respective valve-seats.

The pressure-relief chamber is by the construction described utilized asthe dischargechamber for the effervescent liquid, whereby the device isconsiderably simplified and the drawing off of carbonated liquid fromthe fountain without excessive foaming greatly facilitated.
